We look at the division of 311803 by 7 
We're looking to find how many times 7 goes into 311803.

Going ahead to step 1:
The number 7 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 7

Step 2:
If we divide 31 by 7, we get 4 and a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 28 from 31, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 7

On to step 3:
7 can be fit into 31 4 times, resulting in a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Subtracting 28 from 31 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 7

Step 4:
If we divide 38 by 7, we get 5 and a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 445.0
If we subtract 35 from 38, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 7

On to step 5:
30 divided by 7 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4454.0
If we take 28 away from 30, we end up with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 7

On to step 6:
If we divide 23 by 7, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 44543.0
If we take 21 away from 23, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
When dividing 20 by 7, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 44543.2
If we take 14 away from 20, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
When dividing 60 by 7, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 44543.28
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
When dividing 40 by 7, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 44543.285
Subtracting 35 from 40 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
7 goes into 50 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 44543.2857
The remainder is 1 after subtracting 49 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 44543.28571
The remainder is 3 after subtracting 7 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 44543.285714
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
The number 7 fits into 20 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 44543.2857142
Subtracting 14 from 20 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 44543.28571428
Deduct 56 from 60 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 44543.28571428 with a remaining 4e-09.
